IMPROVEMENT IN LEVER-PRESSES.

Specification forming part of Letters Patent No. 160,13 1, dated February 23, 1875; application filed January 11, 1875.

To all whom it may concern Be it known that I, WILLIAM O. WATsoN, of Albany, in the county of Dougherty and State of Georgia, have invented a new and Improved Lever-Press, of which the following is a specification:

My improvement in lever-presses consists of toggle-levers to work the main lever, connected to the capstan by a rope passing over intermediate pulley-blocks in a manner calculated to increase the leverage without the corresponding diminution of the speed consequent to the ordinary method.

Figure 1 is a sectional longitudinal elevation of my improved press, taken on the line 00 w of Fig. 2. Fig. 2 is a plan view, and Fig. 3 is a plan view of a pulley-block combined with the toggle-levers.

Similar letters of reference indicate corresponding parts.

A is the lever for working the follower B. It is worked by the togglelevers O, with which I propose to combine the pulley-block E, to which the rope F is connected at G, and passes over the pulley H, fixed in stationary supports I of the frame; thence back over the pulley J in block E, and thence to the capstan K, going over a guide-pulley, L.

By these pulleys H and J the leverage is largely increased, While the motion is not materially reduced, on account of the pulley J moving with the block.

The pulley H may be dispensed with, and the rope attached to a permanent object in its place with good results; but a greater leverage is obtained with than Without it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of the block E, pulley J, and the pulley H with the rope F, capstan K, and the press-lever A, substantially as specified.

WILLIAM O. WVATSON.
